Redmi’s official microblogging has announced that it will release a full series of Redmi K40 Sound Quality levels up, supporting Dolby Atmos and Hi-Res audio. The K40 series phones have Dolby Atmos certification, which eliminates crosstalk and simulates the noise around the spatial. Also, the Redmi K40 series phones are certified with Hi-Res high-resolution sound quality and Hi-Res high-resolution wireless audio.

The standard was introduced by Sony and was recognized by the Japan Audio Association, the Consumer Technology Association (CTA), Digital Entertainment Group (DEG), and major record labels and recording companies. Audio files are required to exceed the standard CD sound quality specifications, such as 24bit/192kHz; The parameters of the audio playback equipment must also meet certain requirements.

For gaming to blockbuster movies, from high-end movie theaters to home theaters, the name often comes after shocking audios and visuals. Now, with the help of Redmi K40, this technology is equipped with built-in stereo speakers and the sound can be felt from all sides with a sense of space.

How does Dolby Atmos work in Redmi K40 Explained by Mahesh Balakrishnan:

The Redmi Mobile official introduced the Redmi K40 Series Dolby Atoms technology policy principle, starting with the psychology of high-sound technology research and development, dual-speaker but the word can create a definition of sound around the direction.

The article shows that Dolby Atoms can be used to render any type of sound as a single audio element – separate from the rest of an audio object track. Whether the child is screaming, the helicopter is flying or the car is crashing, content creators can determine where the effects of the sound are coming from and where they should move as the episode progresses. Audio objects can be placed or moved anywhere in a three-dimensional space, including any of the above.

Most headphones and built-in speakers for mobile devices have left and right channels. To create realistic height and surround sound perception, a two-channel mobile system should first have a head-related transport function (HRTF). HRTF describes how sound sources from different locations around us reach our ears.

Streaming Dolby Atmos simultaneously mixes up to 128 supports on audio objects and contains metadata to describe the position of each object in space. Dolby Atmos processors on mobile devices can apply multiple HRTFs to this metadata to reproduce this spatial information on stereo signals. When heard through headphones, the stereo track accurately simulates theatrical sound (including overhead sound), creating an exciting and spatial experience.

Additional processing is required to reproduce the same experience through the device’s built-in speakers. The speakers create a natural “crosstalk” in our ears, which is not suitable for simulating multiple channels. Dolby Atmos processors eliminate this crosstalk and then apply HRTF to create a multidimensional sound field and trajectory of audio objects.

Last month, Lu Weibing announced last month that the machine will use the Snapdragon 888 processor top version will use a 108MP main camera. This will be Redmi’s first smartphone with a 108MP camera. For recent information shows that the low version will use the Snapdragon 870 processor and the smartphone will come with a 4500 mAh battery but no information on the charging capacity. This phone will also use LPDDR5 memory and UFS 3.1 flash memory. According to Xiaomi, this “may be the most expensive straight screen in the industry”. A recent leak shows that this device will come with a 6.81-inch display with a resolution of 3200 x 1440 (2K).
